Hi Thomas,
Agree with Ian and Jose, blade (or what is left from it), guard and scabbard are from a Visayan Tenegre. Hilt is not Batak for sure. I guess that it's a composition from a former collector or seller.
I was interested only for the guard since a similar one from one of my tenegre is broken but the auction went far to high only for a guard.
Regards,
Detlef
